Abstract

Abstract

V-Mo/Ti de-NO_x catalysts were prepared by two kinds of TiO₂ with different BET surface area. XRD, N₂-adsorption, H₂-TPR, Raman, NH₃-TPD, O₂-TPD, and SO₂-TPD analysis were used to characterize the physiochemical properties of the different catalysts. The catalytic performances of the catalysts were tested via a fixed-bed micro-reactor, and the SO₂/SO₃ conversion of the different catalysts were tested through a pilot-scale reactor. The results show that the catalyst prepared by TiO₂-A and TiO₂-B (75%:25%) possesses lower content of the polymeric vanadate, higher reducibility, relatively lower acidity, and higher O_α amount than that of the catalyst prepared with pure TiO₂-A. As a result, the former catalyst exhibits higher catalytic activity. However, the acidity of the catalyst decreases obviously when 50% TiO₂-B is used, leading to the decline of the catalytic performance. What is more, the using of TiO₂-B can decrease the SO₂/SO₃ conversion of the catalyst. Overall, the catalyst prepared with 75% TiO₂-A and 25% TiO₂-B displays the best catalytic performance.
